Good morning AC,
I love that you have brought this out about the serpent.
It is believed that Genesis was written by Moses. I would say that Moses probably knew little or had never heard of the theory of ‘evolution’. Yet here, the Bible seems to record that serpents (snakes) at one time did not go on their bellies.
I have a large snake, a Yellow Anaconda, named Ducky. If you look on him, he has, near his tail, two spurs. These spurs are attached to small skeletal pieces. Evolutionists will call these ‘vestigial legs’.
Shortly after I got married almost 4 years ago, I was telling and showing my wife these spurs and their ‘explanation’. After a little discussion, we decided to check the Bible.
And there it was, God telling the serpent he would go forth on his belly, from now on. Not ‘evolution’, but Gods command.
You have a great day AC.
